PURPOSE:To deposit charge to a prescribed position with good accuracy by providing a chute which is movable simultaneously in the height, circumferential and radial directions of a moving bed type reaction furnace such as a blast furnace to the inside top of said furnace. CONSTITUTION:A movable stand 15 which is vertically movable is provided to the inside top of a blast furnace 1, and a rotary stand 14 which is made rotatable around the axial core of the furnace is provided thereto. A guide 18 is provided thereto in such a way that the guide can move back and forth in the diameteral direction of the furnace 1. A funnel-shaped chute 10 which is made into a funnel shape and is provided with a passage inclined to one direction is provided to said guide. Driving devices 11, 12, 13 are driven to move the chute 10 in the height, circumferential and radial directions of the furnace thereby depositing the charge fed from a hopper 7 at the furnace top through a flow rate regulating valve 8 to the prescribed position. |
